The poles have a high pressure. I know it has a high pressure but not exactly why.
I think because of the sinking air, the air that got cold. You should know the cells etc.
BUT IT's HIGH PRESSURE.
IMPROVE:
It has to do with the prevailing winds and atmospheric shiftings.
I hope you've heard of prevailing winds. They're the winds that blow constantly in one direction over the entire globe. It's just like how people say that the smoke factories in Ohio are blown north eastwards towards New York. There's a global movement of air that separated into three different cells per North/South hemisphere.
Anyway, the poles have their own prevailing winds cell, and blow westwards, called the polar easterlies. A cell is a continuous circular system of wind, meaning air is blown across the ground, then it rises, goes back over, and is blown across ground again. Air in the 60* latitude rises, moves back towards the poles, then sinks again, which causes all the high pressure. This continuous high pressure also causes the lots of dry air that blows down from the north, as well as the generally sunny (or cloudless, if it's nighttime) skies found in the poles.

Air masses originate in polar and subtropical?
high-pressure belts
What is an air mass that forms over dry land?
Continental air masses. Tropical air masses form over water.
What type of air masses would form over the northern Atlantic?
Maritime polar air masses.
Polar air masses are cooler than tropical air masses because the place where they start I what?
Polar air masses are cooler than tropical air masses because they originate from high-latitude regions closer to the poles, where temperatures are generally colder. Conversely, tropical air masses originate from low-latitude regions near the equator, where temperatures are generally warmer. This temperature difference between the two regions accounts for the inherent temperature contrast between polar and tropical air masses.
A contienetal polar air mass forms in?
A continental polar air mass are cold to cool and dry, but are not as cold as the Arctic air masses. Continental Polar air masses form over Canada and Siberia. These air masses bring cold air during the winter and cool, relatively clear, rather pleasant weather in the summer. The air mass is stable and usually prevents cloud formation.
Do polar air masses have air pressure?
yes
Air masses originate in polar and subtropical?
high-pressure belts
Which type of air mass brings cool humid weather to the West Coast of the United states?
Maritime tropical air masses, Maritime polar air masses, Continental polar air masses, or Continental tropical air masses.
What are the types of air masses?
The 4 major air masses are continental polar (cP), continental tropical (cT), marine polar (mP) and marine tropical (mT). Generally, continental air masses are drier than marine air masses, and polar air masses are cooler than tropical air masses. cT air masses are relatively limited in distribution existing in the south west North America and North Africa.
What are polar air masses?
Cold, wet air.
What types of air masses that affect Saskatchewan?
Continental polar air masses would mostly affect Saskatchewan. There may also sometimes be maritime arctic and maritime polar air masses.
What is an air mass that forms over dry land?
Continental air masses. Tropical air masses form over water.
What is the four different air masses?
The 4 major air masses are continental polar (cP), continental tropical (cT), marine polar (mP) and marine tropical (mT). Generally, continental air masses are drier than marine air masses, and polar air masses are cooler than tropical air masses. cT air masses are relatively limited in distribution existing in the south west North America and North Africa.
How are continental tropical and continental polar air masses and how are they different?
the continental tropical and continental polar air masses both come from land, are humid and their differences are polar is cool air while tropical is warm air
What air masses are in alaska?
polar continental
What type of air masses would form over the northern Atlantic?
Maritime polar air masses.
What are the 5 types of air masses?
The five types of air masses are polar, tropical, maritime, continental, and arctic. Polar air masses are cold and dry, tropical air masses are warm and dry, maritime air masses are warm and moist, continental air masses are dry and cold, and arctic air masses are extremely cold and dry.
